Manufactured by Lake City Army Ammunition Plant the 5.56x45mm XM855 62 Grain SS109 Green Tipped Steel Penetrator Lead Core Mil-Spec ammunition is bulk packed loose 1,000 rounds in a box. This ammunition is boxer primed, sealed primer and projectile.reloadable brass cased and not packed in individual boxes because the military likes it loose. Save money by buying it in this 1,000 round loose bulk pack.

Lake City 5.56 Ammo is arguably the best 5.56 Military ammo manufactured. This is the original US Military Lake City XM855 ammunition loaded with SS109 penetrator projectiles, brass cased ammo firing at 3,025 fps. This is identical to the ammo issued to the US military.

Note: This is military grade ammunition. It will show discoloration which is caused by a process known as annealing. This is completely normal. The cases may also have minor dings from being bulked packed.

Best SHTF ammo out there - 1/13/2013

Reviewer:

Randy

If you expect to have a confrontation with an enemy force that may take cover behind brick walls, vehicles, etc. then that's what I'd think this ammo is built for. In my testing, this ammo will penetrate over 1/4" steel at 200m+, car engines, and brick walls. I can't say with any confidence/good conscious standard 5.56mm ammo is any good for the above purposes. In fact, I'd say it's just worthless. I wouldn't want to put my life on anything less than the M855, as I'm former military (infantry), so believe me that I'm giving sound advice.
I'd like to deny that this ammo is any good and just horde it for myself, but people are buying it up at any cost because they know it's the best, even if it's XM855 (rejected for military/battlefield use - designated training only/dump on the civilian market).
If you're just looking for some rounds for target practice or against a single home invader, please don't buy this ammo and let others have the opportunity to buy it who have more serious purposes in mind, such as SHTF scenarios. Also, always sight your weapon in with the ammo you primarily intend to use, or else accuracy will suffer in unpredictable ways. Also, the M855 round is designed to be used with the M856 when needed for tracing a path to the target at night, whether it be personal, vehicles, or aircraft.

worst dented brass ever - 4/1/2011

Reviewer:

disapointed

I have bought tens of thousands of rounds of 5.56 in my lifetime, including tons from lake city and this is by far the worst brass i have ever seen, at least 60% had dented brass, I have seen people comment on "a few dings" this case is at least 30% unusable, these are not dings they are large dents and i will not even chamber these rounds, been a fan of lake city for years, dont have a clue what happened with this case, all i can say is that demand must be up and quality is way down.

Can Hit a Car - 12/7/2010

Reviewer:

HiSierra

About the best you can say is that this ammo Feeds and Goes Bang! At 35 yards it may shoot an 8" group; or a 3" group with a flyer or two. It wanders all over the place. Very inconsistent ammo. Good for hitting a car at 100 yards. Or CQB practice

Excellent Target Ammo - 2/20/2013

Reviewer:

Ken

I've purchased this ammo a few times as I use a Knights Armaments M-4 platform for duty. The ammo has always been reliable, performed well with the rifle, and has been smooth feeding. It ISN'T pretty, or the most accurate ammo out there but there is no reason you can't get a 4 inch group at 200 yards.
